Upon my arrival, the welcoming and friendly atmosphere of the premises was immediately noticable and immediately put me at ease. As for the eye test itself, this was most thorough and unhurried. The modern equipment available to David allowed for an accuarate assessment of my eyesight - in my case one eye slightly weaker than the other but not worryingly so. The various stages of the examination were fully explained by David. Although I may not need to have a further sight test for another two years or so, I know for sure where I will be going for it. And I would certainly pass on the details of Harefield Opticians to anyone I may come across who is enquiring about their own optical needs.
